TO ALL WHOM IT MAY CONCERN:

Be it known thatl', WILLIAM RHODES ARNOLD, of Providence, in the countyof Providence, and StateV ci' Rhode Island, have invented a new andimproved Machine for Measuring and Lapping Tape and Braid; and I dohereby declare Vthat the following is a full, clear, and exactdescription thereof, which will enable others' skilled in the art tomake and use the same, reference being had to the accompanying drawings,forming part of this specification, in'whieh- Ifigure 1 is a-perspectiveview of my invention. v

Figure 2 is a detached front view of the muin driving-wheel.

Figure 3 is a central cross-section taken on the line a; zu, iig. 2.

Figure 4 is a detached view ofa guide-pin. i v Similar letters ofreference indicate like parts.

The object of this invention is to measure tape, braid, bindingor othersimilar goods, into exact lengths for the trade, sayin piecesiive yardslong, and at the same time form them into sticks by lapping or folding.vUpon a solid base, Aure secured two standards B B., upon and betweenwhich is hung a plate spur-wheel C, to bcturned by hand with the crankD. The spur-wheel C gears into a pinion, E, above on a lsliding-shaft,a, which has its bearings in thestandards B B. Just within thc peripheryof the gear-wheel C, on the side of it, is placed a cam, b, whichextends around nearly or quite one-half of the circumference ofthewheel, as shown in iig. 2. The face of the cam b is in the plane of theside of the plate-wheel C, and projects above the plate-faceone-half-incln as shown in iig. 3. One end ofthe cam is bevelled, andthe other end has a nose or projection, Z1',` lto form a recess behindit. vOn the inside ofthe standard B, at the lower part, is fastened oneend of a spring, e, which extends up and terminates in a fork, c', whichclutches or clasps the shaft a between the ring-shoulders i :Zd thatconfine its uiovement'on the shaft..- A pin, g, having'a hooked outerend, z, is fastened on the spring c, so that the ends of the pin maystrike the dat platefacc of the wheel O, and the hook 7i lie in therecess-behind the projection 5 on the cam I). The shaft a may be movedin its bearings lengthwise, so as to press the upper end of the spring coutward, and raise the pin y so that the hooked end h will lie upon thecam when necessary, as hereinafter described. On the end of thesliding-shaft a, outside of the standard B', is aiiixed a pair oflapping-bars, it', which for ordinary use are made about seven inchesapart, and :is-the gear-wheel C is made proportioned to the pinion E, soas to give the shaft a fourteen turns in one revolution, a stick of veyards of braid isformed on'the lapping-bars i z' for each revolution ofthe gear-wheel C.

When the machine is started, an end of the braid having been caught onahook, c, on one of the lappingbars z', the shaft a is pushed forward sothat the end of the pin g is mounted on the cum I) at the projecting endb. The gear-wheel C is then turned until the pin g slips off lthe cam atthe opposite inclined end, when it coutinues to travel around on theface of the plate of the wheel O until the hook L passes into the recessbehind the projection b', and thus stops the machine. It will beobserved that during this revolution of the gear-wl1eel C, the turningof; the lapping-bars z'z'has folded or lapped around them a. piece ofbraid or tape of a definite length, fed from a suitable fra-me, as shownin red, and the length of braid thus folded or lapped has been formed intwo parts, folds, or laps, by the action of the spring c, which hasforced the shaft a backward in its bearings the thickness of the cam lbon which the 'guide-pin g travelled when the pin slipped from the cam.One of the laps or parts of the length of braid thus folded was madeover one point or part of the lapping-bars z' i, while the pin g movedon the cam b, andthe other part while it moved the balance of therevolution of the gear-wheel C over its plate-face. The length is thenmade into what is known to .the `trade technically as a stick of braidby the operator cutting it off and turning one end under.. To start themachine again, the .gear-wheel C is turned back just enoughy to releasethe hook i of the pin g from the projection b of the cam b, when theshaft a is pushed forward, so as to raise the end of the pin g upon thecam I), for repeating the operation of lapping and measuring a pieceofihraid, as before described. v

Having thus described my inventi on,I claim as new, and desire to secureby Letters Patent* 1. lhc machinery for measuring and lapping braids,tapes,-&c., having a shifting and4 positive stopmotion, substantially asheroin described.

2. The sliding-shaft a, the spring c, thevpin g, and the cam b'on thegear-wheel C, combined and operatingY substantially as and for thepurposes herein described.
